Needless to say, we turn it off and rain most of the winter which is a pain in the butt. Eventually, we'll have rainwater collection for the tiny house and the mobile home that will replace the hoop house on the site. All of that water comes from the main well that supplies the main house.
I'm in Massachusetts. And although the winters have been fairly mild the last couple of years, there's always freezing anyway.
So, what could work for insulation for overland hose. We don't want to dig it in for a lot of reasons.

But how much insulation do you need? Maybe R-30 for the 30in of soil to the frost depth. So now that we have an idea of how much insulation you need. What could be use for insulation?
You could insulate with:
hay/straw (R-30 aka 15inch)
earth/compost (R-30 aka 30inch)
rockwool (R-30 aka 7inch)
foam/etc (R-30 aka 7inch)
I would probably double all of those numbers, just to be on the safe side.
You could get a recirculating pump to make sure that the entire lenght of pipe have the same temp and it isn't freezing in some section. Maybe even turn on a hearter once the temp of the pipe get down to a specific temp say 40F.
